Now,

"Tell me , I'm not in the blue. That I'm not wasting my feelings on you. Every time I looked at you , my heart is jumping , what can I do. You drive me crazy , crazy , crazy , I'm into deep. You know I'm crazy , crazy. Baby thinking of you keeps me up all night"

-U Drive Me Crazy / Crazy by Glee Cover (original Britney Spears)
